Background: There is scanty evidence regarding the magnitude of COVID-19-related psychological distress (PD) among the general population of India. Objectives: This study aimed to estimate the pooled prevalence of PD among the general public of India during the COVID-19 pandemic. Material and Methods: We conducted a meta-analysis of 21 online surveys conducted across the Indian subcontinent and published between 2020 and 2021. Results: Overall estimates of PD among the general public during the COVID-19 pandemic by the random-effects model is 33.3% (95% confidence interval: 23.8%-42.8%; n = 21 studies). The level of heterogeneity was high among the included studies (I2 = 99.67%). In subgroup analysis, it was found that the survey tool and the methodological quality had a significant effect on the overall prevalence estimates. Approximately 33% of the general public reported to have PD during the COVID-19 pandemic in India, although the overall prevalence varied based on survey tools and quality of studies. Conclusion: As the pandemic crisis seems to be ebbing across the world, the current findings are a wake-up call to devise pragmatic strategies to curtail the burden of similar pandemics and to successfully meet the challenges ahead.

Psychological distress (PD) is an indicator for assessing the mental health of the population in epidemiological studies and as a health and psychological outcome.[1] The PD is a state of emotional turmoil and has diversified meaning as per the context. It is widely agreed that, it is a state of emotional insufficiency or emotional distress.[2] COVID-19 pandemic has severe physical, emotional, and psychological consequences which were novel to the society. With the global pandemic, these “silent” and insidious issues can go unnoticed.[3] The common response to COVID-19 is confinement to physical spaces, lack of mobility, loss of income, isolation from the family and friends, powerlessness, helplessness, and affecting the overall well-being of the individual and community during the lockdown. Uncertainty and insecurity of the future might have resulted in more symptoms of PD.[4]
As the pandemic seems to be ebbing with the impending uncertainty and the emergence of a new strain of the virus, there is a potential for yet another wave, which demands preparedness at the individual, family, and community levels.[5] A large and sufficient number of national and international studies serve a better understanding of PD during the pandemic. This pandemic period has taught the requirement of empirical data to devise the preventive mental health strategies to diminish perceived distress and augment subjective psychological well-being to manage the crisis.[6] Every individual has varying degrees of PD due to COVID 19 and the effect of the virus and related pandemics poses much uncertainties among general public.[7] This warrants immediate attention of the researchers and policy makers to identify the pandemic's aggregate burden, which is untapped. Hence, the present study is aimed to identify the empirical literature on the pooled prevalence of psychological distress among the general public of India during the COVID 19 pandemic.
MethodsArticle search strategy
We searched, PubMed, Wiley online library, Science Direct, APA Psych Info, Proquest, and Google Scholar with the following keywords: “general public,” “COVID-19,” “psychological distress,” and “India” following the Preferred Reporting Items for Systematic Review and Meta-analysis[8] guidelines to retrieve potential studies for the review. The search was performed for articles published between 2020 and 2021 [Figure 1]. Finally, 22 studies were found suitable for systematic review in which one study did not specify the cut-off score of the outcome measure, and the same was excluded in the meta-analysis (n = 21). The detailed search strategy is described in Supplementary Material 1.
Eligibility criteria
Our inclusion criteria were studies conducted in India; studies reporting PD, the population included the general population. PD was operationally defined as the measurement of stress during COVID-19 based on validated standardized screening tools. Our exclusion criteria were studies conducted outside India, specific populations such as health-care personnel, police personnel, reviews, case reports, and qualitative studies. Further, studies with inadequate data and outcome measures other than PD such as anxiety and depression, and psychiatric illness were also excluded.
Data extraction and quality assessment
The data extraction was carried out based on the following study characteristics: author (period of study), study setting/study design, gender, sample size/sampling method, age in years, survey tool, and the prevalence of stress. The “JBI Critical Appraisal Checklist for Studies Reporting Prevalence Data”[9] was used for the risk of bias assessment of the included studies. The total quality score was ranging from 1 to 9 in which the risk of bias was categorized as follows: high (0–3), moderate (4–6), and low (7–9) risk of bias.
Statistical analysis
Open meta-analyst software was used to perform this meta-analysis. Assuming the significant inconsistency among the studies, a random-effects meta-analysis model was used and I2 statistics were calculated to measure heterogeneity among studies. The funnel plot and Egger's regression tests were used to assess potential publication.
ResultsStudies included in our meta-analysis are shown in [Table 1].[10],[11],[12],[13],[14],[15],[16],[17],[18],[19],[20],[21],[22],[23],[24],[25],[26],[27],[28],[29],[30],[31] All 22 included studies were conducted using online cross-sectional surveys using the snowball sampling technique by distributing the Google form through Facebook, WhatsApp, or Twitter. In 16 of 22 studies, the online survey was conducted across India, while in others, it was conducted in selected states/states. The sample size of included studies varied from 159 to 2317. The number of male subjects in the included studies varied from 95 to 1160 and the female subjects varied from 56 to 1541. The age of the participants varied from 15 to 70 years. In eight studies, the stress was assessed using the Depression, Anxiety, and Stress Scale-21 (DASS-21); Impact of Event Scale-revised was used in four studies and Perceived Stress Scale was used in three studies. Other scales used to assess the PD included General Health Questionnaire (12 and 28) in two studies, The 5-item World Health Organization Well-Being Index In in one study, Kessler PD Scale in one study, and K10 in one study. Most of the included studies were found to have a moderate risk of bias (n = 15) and the median score was 5 (mean-5.23; standard deviation -1.2). Four studies were found to have a low risk of bias (7/9). The risk of bias assessment of the studies is summarized in [Table 2].

The overall estimates of PD among the general public during the COVID-19 pandemic by the random-effects model are 33.3% [95% confidence interval (CI): 23.8%–42.8%; n = 21 studies, [Figure 2]]. There was a significant heterogeneity on the outcome measure (I2 = 99.67%, Q = 6073.155, P < 0.001, Tau Squared = 0.049). Nonsignificant eggers test value (P = 0.34) and a reasonable symmetry of the funnel plot did not reveal any source of publication bias [Figure 3]. In sensitivity analyses, no significant effect of any particular study was found on the overall pooled estimates in which the values ranged between 30.7% (21.6%–39.8%) and 34.5% (24.6%–44.4%).

Subgroup analysis was performed based on the screening instrument tool and risk of bias assessment [Table 3]. The pooled prevalence of PD was significantly lower based on DASS-21 measurements as compared to those with studies other than DASS-21 scales (15.0%; 95% CI: 09.8%–20.1% vs. 43.0%; 95% CI: 31.2%–57.6%). In terms of methodological quality, studies with moderate risk of bias showed higher prevalence (32.3%; score-3–6) as compared to those with low risk of bias (19.1%; score >7/9).
Table 3: The prevalence of psychological distress using random effect model by subgroup analyses DiscussionThe present meta-analysis is a pioneer study that elucidates the aggregate estimates of COVID-19-related PD based on the observational studies conducted among the general population of India. Our findings suggest that approximately 33% of the general public reported having PD during the COVID-19 pandemic in India.
There are certain caveats to generalize our findings. The results are purely based on online surveys conducted across the various parts of the country. To address the imposed restrictions of COVID-19, the majority of studies distributed questionnaires to an unknown broader audience posing some serious methodological limitations in the form of sampling bias and respondent bias.[32] There was a significant inconsistency among the included studies as the level of heterogeneity was high (I2 = 99.67%). This was evident in the subgroup analysis in which the survey tool and the methodological quality significantly affected the pooled prevalence. The recent meta-analyses reported relatively similar rates of PD (26%–37.3%) in the general population during the COVID-19 pandemic globally.[33],[34]
The psychological impact of the pandemic is largely influenced by certain factors such as onset and burden according to nations, availability of pandemic preparedness. This might be the reason for the wide variation in the average prevalence of COVID-19-related PD in the existing literature.[35],[36] It is worth noting that our pooled prevalence is based on the representative number of studies (n = 21) as compared to the similar meta-analyses where the findings are reported based on a meager number of studies (n = 6). We have not included studies without a standard survey tool or cutoff scores reflecting the scientific worth of the magnitude of the outcome measure from an Indian general public perspective. Moreover, there was no significant effect of any particular study on the overall pooled estimates in our sensitivity analyses in which the values ranged from 30.7% to 34.5%. However, considering the methodological limitations, the current findings should be interpreted accordingly.
The pandemic crisis seems to be ebbing and almost all parts of the world are returning from their new normal to a normal rhythm. This wake-up call makes the governments around the world devise national strategies to curtail its spread and must re-engineer the way they operate to successfully meet the challenges ahead. There is a need for regular interaction and emotional support from friends, family, partners, caregivers, community, and social media to minimize psychological stress.[37] Further it is the requirement for a preventive mental strategy on maximizing positive mental health, diminishing perceived distress, and augmenting subjective psychological well-being to manage the crisis. It is the optimal time to design the targeted approach through the online resilience initiatives to reduce PD on a large scale with low cost in time of crisis.[38]
Strength and limitations
The major uniqueness of this study is its novelty of a meta-analysis based on a representative number of studies reflecting the magnitude of the COVID-19 related PD from an Indian general public perspective. Most of the included studies were found to have a moderate risk of bias and the separate analysis-based screening tools further add the scientific worth of the evidence. Despite the strengths, there are certain limitations to our findings. The outcome measures are based on web-based surveys in which the sample might be contaminated by respondent bias. The level of heterogeneity of the included was high and pooled estimates varied as per survey tools quality of studies.
ConclusionApproximately 33% of the general public reported having PD during the COVID-19 pandemic in India, although overall prevalence varied based on survey tools and quality of studies. As the pandemic crisis seems to be ebbing across the world, the current findings are a wake-up call to devise pragmatic strategies to curtail the burden of similar pandemics and to successfully meet the challenges ahead.
